FIELD: physics.
SUBSTANCE: invention reveals a protecting structure for the protected document, containing a transparent carrier and metal elements held by the specified carrier that form the identifying pattern. Herewith the identifying pattern provides the ability to identify information by using the identifying pattern in conjunction with the revealed element, and the thickness of the metallic elements is small enough so that the metal elements are transparent, wherein the varnish is at least partly imposed on the metal elements.
EFFECT: improved visibility of the protective element.
